Kashmir has never been an integral part of India- Indian Booker Price winner

Arundhati Roy, the Booker Prize winning author, had said on Monday Oct 25 “Kashmir has never been an integral part of India. It is a historical fact. Even the Indian government has accepted this.”
A senior Congress leader on Monday asked noted to withdraw her statement on Kashmir.

The former Union Minister said that Roy , must withdraw her statement which is contrary to historical facts and miss lead the nation and as well as international community. And it was really surprising to see such an irresponsible statement from someone who is one of the country’s best-known writers.

He said that she would to better to brush up her knowledge of history and know that the princely state of Jammu and Kashmir had acceded to the Union of India after its erstwhile ruler Maharaja Hari Singh duly signed the Instrument of Accession on October 26, 1947.

Arundhati Roy, claimed that she had called for justice in her speeches especially about justice for the people of Kashmir who live under one of the most brutal military occupations in the world.

Background of India and Pakistan conflict

India and Pakistan have a long and complicated history with each other. Both countries fought three wars between 1947 and 1972, with Kashmir as the main battleground. Ever since, Kashmir has been in pieces, with India and Pakistan occupying most of it, and China a small portion. Both India and Pakistan claim all of it to be rightly theirs.
The conflict traces its roots to 1947, when India and Pakistan were formed from former British colonies in South Asia. Pakistan was formed from the majority Muslim part of British territory, and India from the majority Hindu part.
The state of Jammu-Kashmir, with a majority Muslim population but a Hindu ruler, chose to be part of India in a process that many Muslims–and Pakistan–believed to be illegal. The United Nations has issued resolutions calling for a referendum to decide Kashmir’s fate, but India has ignored them. The majority would almost certainly vote for Kashmir to be independent or part of Pakistan.
Almost immediately, India and Pakistan fought their first war over Kashmir. In 1949, the countries signed the Karachi Agreement establishing a ceasefire line–but did not agree to where the final border should be. The ceasefire was supervised by U.N. observers, who have remained in the area from 1949 until the present day.
In 1965, India and Pakistan fought their second war over Kashmir. It only lasted sixteen days, and did not result in any major changes.
In 1971, India and Pakistan fought their third war, this time mainly over the independence of Bangladesh from Pakistan, but a new ceasefire line was reached in Kashmir.
In July 1972, the two countries signed a new agreement defining a “Line of Control”–yet another ceasefire line–in Kashmir. Once again, the countries did not decide a permanent border.
In the 1980s, India rather obviously rigged elections in Kashmir in order to keep its supporters in power. Ongoing corruption, not to mention outright persecution, rape and other human rights violations, bred increasing discontent among Kashmiri Muslims.
